TED STATES PAT WILLIAM THOMAS, OF HINGHAM, MASSACHUSETTS.

CHAIR FOR SHIPS CABINS.

Specification of Letters Patent No. 14,890, dated May 13, 1856.

To all whom t may concern Be it known that I, WILLIAM THOMAS, of Hingham, in the county of Plymouth and State of Massachusetts, have invented a new and Improved Chair for Vessels, and which I'term a Cabin-Chair, and I do hereby declare that the following is a full, clear and exact description of the same, reference being had to the annexed drawings, making a part of this specication, in which- Figure l, is a side view of my improvement, the base being bisected vertically through its center. of the same.

Similar letters of reference indicate corresponding parts in the two figures.

My invention consists in suspending the chair to arms which are pivoted to a suitable frame connected with the base, and arranged as will be presently shown and described, whereby the chair will remain stationary while the base or framing will move or rock with the vessel.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A, represents the base of the chair, which may be constructed of wood or metal, and of any desirable form, with a socket (a) attached to receive a spindle or arbor B, to which a bowed or semi-circular shaped bar C, is attached, said bar having a circular plate (o) attached to it, which plate rests upon the upper end of the socket. The bar C, is allowed to turn freely around upon the socket (a).

D, represents the chair, which is made of such a size as to t within the curved bar C. To the upper ends of the bar C, there is attached a curved bar E; the ends of the bar E, are attached by pivots (c) to the ends of the bar C, so that the bar E, may swing back and forth.

Fig. 2, is a front ViewY F, F, represent arms which are pivoted at their centers to the bar E, near its ends, and the front end of the upper part of the chair is attached by chain (d) to the outer ends of the arms F. The inner ends of the arms F, F, are connected by chains (e) (e) to the ends of an arm G, which is pivoted at its center to the lower part of a bar H, attached to the center of the curved bar E. The upper part of the chair at its back is connected by a link and hook (g) to the upper end of the bar H.

By this arrangement it will be seen that the base A, may be moved or rocked in any direction, and the chair D, will remain stationary, and the chair being attached tc the bar C, a considerable distance above its center of gravity, it will not conform to the motions of the base and vessel.

The above invention is designed for vessels, and to prevent sea sickness, and the annoyance occasioned by the rolling of vessels. .The improvement is applicable to sofas and settees, as well as chairs.

I do not claim suspending or attaching the chair to a base or frame, so that it will remain stationary while the base or frame is moved or rocked, irrespective of the peculiar manner of attaching or suspending the same, but

IVhat I do claim as new, and desire to secure by Letters Patent, is-

Suspending or attaching the chair D, to the curved bar C, which is connected to the base A, by means of the arms F F, G, and curved bar E, arranged substantially as shown and described, for the purpose specified.

WILLIAM THOMAS.
